Bently Nevada 3500 25

1. Overview

The Bently Nevada 3500/25 is an enhanced keyphasor module specifically designed for use in the Bently Nevada 3500 series machinery protection and condition monitoring system. It is responsible for converting analog signals from keyphasors or proximity sensors on rotating machinery into digital keyphasor signals, providing a time reference for subsequent vibration analysis and fault diagnosis.
